No more a tool of the devil than any other thing in this world. It ONLY becomes his tool if folks use the tool to do the devils work. Social media can ALSO be used to witness for the Lord, and reach many folks that may well not be reached otherwise.
Comparing ourselves is not always an evil spirit........might wanna do a bit more reading of Scripture on that one.... just saying
A few years ago, I was invited to join a mission team to go minister to an underground church and ministry in Vietnam. Most on the team were on their Facebook, asking for resources, prayer and others things for this trip. Their churches were also on their Facebook pages, promoting their would be missionaries and the trip.
We were in a launch meeting one Sunday night and all received notice from the Evangelist that organized the trip that it was cancelled and that the underground church had been raided and all members and their families, tortured, maimed, raped and eventually killed, including the pastor and his entire family. They found the pastor tied to a tree in the jungle with 1 inch strips of his flesh cut off and exposed. The autopsy said he lived for at least 7 days while all manner of vermin and insects and birds slowly ate him alive. the same was done to his wife and 3 small children and not one child of his was over the age of 8 and they were all found together tied to trees about 5 feet apart.
The trip was cancelled because groups that kill , kidnap and torture Christians in Vietnam use Facebook to track mission teams and their movement in and out of their country. Someone had decided to post our hotel location and the enemy found the church. If the church had not been attacked and the trip was still on everyone but 4 of us would have been kidnapped and died. The group responsible had already been making plans to kidnap everyone that posted about the trip on Facebook.
This would not be dying for the cause of Christ, this would be letting Satan kill prideful, foolish, naive, and very stupid Christians
No Christian states they would ever take the mark of the beast, but happily deceive themselves with social media, because they have generally no understanding that it is the technical platform by which they will one day be hunted down, persecuted and killed for the cause of Christ even in the USA.
Social Media is just another beast technology, just like crypto currency, like bitcoin and Ethereum
Social media divides it never unites. You can attmept to justify all you like, but if people got off Facebook and in THE BOOK, we might see the world change for the better.
